Selection Issues

Unity Engine
1

I have a map with 4 different types of icons on it. On the top of the map there are buttons which allow you to choose which icon is displayed. I’ve written a script that stops rendering the non-chosen icons but they are still selectable as their colliders are still active. I tried disabling the whole Game Object but then I couldn’t turn them back on. As far as I know, you can’t turn on and off a collider so I’m a bit stumped. Any suggestions?

function SetIcons () {
    var AllIcons : BoxCollider[] = FindObjectsOfType(BoxCollider) as BoxCollider[];
    for (var IconType : BoxCollider in AllIcons) {
        if (IconType.gameObject.GetComponent.<MainMenuTapToGo>().whichIcon != WhichIconSet){
        	IconType.gameObject.renderer.enabled = false;
        }
        else{
        	IconType.gameObject.renderer.enabled = true;
        }
    }
}

The worst possibility you have is to destroy the collider and recreate it. Does this help?

Keep a reference to the GameObject so you can turn it on/off, avoiding the Find methods that are slow and don’t return inactive GameObjects.
If you only want to disable Colliders you use Physics.IgnoreCollision.

Thanks for the suggestions. I probably should have mentioned that this script is for an iPhone. I was hoping that there might be a simple way to filter which information was displayed on the map so that it was possible to then select a specific item.

Using the above script, destroying the collider would result in the object being removed from the search criteria. I could probably search by script instead though.

An array of the objects would probably be the most efficient.

Are there find methods which return inactive objects?

I was thinking that I could possibly just shrink the size of the collider so that it’s effectively off.

Thanks again.
